Is it permissible for a Muslim woman to marry a Muslim whose parents are not Muslim and do not speak Arabic, and will their marriage be successful and blessed?

There is no objection to a Muslim woman marrying a Muslim man, even if his parents are disbelievers, provided that the conditions for marriage are met and its impediments are absent, for "And every soul earns not [anything] except for itself, and no bearer of burdens will bear the burden of another." The marriage will be blessed and successful if both spouses are righteous and of good character; as the Prophet, peace and blessings be upon him, said: "If there comes to you one whose religion and character you approve, then marry [your daughter] to him." Among the reasons for understanding is for the spouses to come from the same environment and speak the same language, but this does not mean that the marriage will not succeed if this is not achieved.
